The sub-base layer serves three functions. First it protects the sub-grade from over stressing. Second it provides a platform for the wear course layer. Third it serves as a drainage and filter layer. The United States Department of Transportation generally recommends that the minimum soaked unconfined compressive strength requirement for a cementitious sub-base be at 250 psi or greater. Soils and Sand stabilized with a very low dosage of our Envirotac line of polymers can easily achieve a soaked UCS many times greater than 250psi. Use Envirotac to create a stable and durable sub-base that when constructed will cater to heavy traffic and can absorb more deflection than any other stabilizer available on the market.
